(EN) VOCAL AND INSTRUMENTAL AUDIO EFFECTS
(FR) EFFETS AUDIO VOCAUX ET INSTRUMENTAUX
Abstract
(EN)
Systems, methods, and computer program products are provided for producing audio and/or visual effects according to a correlation between reference data and estimated note data derived from an input acoustic audio waveform. Some embodiments calculate a pitch score as a function of a pitch estimate derived from the input waveform, a reference pitch, and a real-time-adjustable pitch gating window. Other embodiments calculate the pitch score as a function of pitch and timing estimates derived from the input waveform, reference pitch and note timing data, an adjustable rhythm gating window, and an adjustable pitch gating window. The audio and/or visual effects are produced according to the pitch score, and may be used to generate outputs (e.g., in real time) for affecting a live performance, an audio mix, a video gaming environment, an educational feedback environment, etc.

Des systèmes, des procédés et des produits-programmes informatiques sont fournis de manière à produire des effets audio et/ou visuels selon une corrélation entre des données de référence et des données de notes prévues obtenues à partir d'une forme d'onde audio d'entrée. Certains modes de réalisation calculent un résultat de hauteur en fonction d'une estimation de hauteur obtenue à partir de la forme d'onde d'entrée, d'une hauteur de référence et d'une fenêtre de déclenchement de hauteur réglable en temps réel. D'autres modes de réalisation calculent le résultat de hauteur en fonction d'estimations d'une hauteur et d'une synchronisation obtenues à partir de la forme d'ondes d'entrée, d'une hauteur de référence et de données de synchronisation de note, d'une fenêtre de déclenchement de rythme réglable et d'une fenêtre de déclenchement de hauteur réglable. Les effets audio et/ou visuels sont produits selon le résultat de hauteur et peuvent être utilisés de façon à générer des sorties (par exemple, en temps réel) de façon à affecter un spectacle en direct, un mélange audio, un environnement de jeu vidéo, un environnement de rétroaction éducatif, etc.
